Definitions

  • the invention is based on a compressed gas switch according to the first part of patent claim 1.
  • Such a switch is known for example from US-A-4,658,108.
  • the known switch has a pressure space with constant volume enclosed by the movable of its two switching pieces.
  • switching gas generated compressed gas is supplied to this pressure chamber, which gas is used to blow the switching arc when the current to be switched off approaches a zero crossing.
  • this saves a considerable amount of drive energy compared to a compressed gas switch, in which the compressed gas used to blow the switching arc is generated exclusively by a piston-cylinder compression device operated by the switch drive, however, with such a switch, an optionally desired increase in the contact separation speed could previously only be achieved by a significant increase in drive energy can be achieved.
  • the invention solves the problem of developing a gas pressure switch of the type mentioned in such a way that its contact separation speed is significantly increased compared to the drive speed without any significant increase in its drive energy and without changing its extinguishing geometry.
  • the compressed gas switch according to the invention is characterized in that it now also masters switching cases in which a high contact separation speed plays an important role. This is particularly important when switching capacitive currents, which can now be switched safely and without any significant increase in drive energy.
  • Both contact pieces 1, 2 are essentially rotationally symmetrical and are each electrically conductively connected to a power connection (not shown). Both contact pieces 1 and 2 each have a nominal current 4 or 5 and an erosion contact 6 or 7.
  • the contact piece 1 can be moved along the axis 3 by a drive, also not shown, and has an insulating nozzle 8 arranged coaxially between the nominal current 4 and erosion contact 6 and rigidly connected to the nominal current 4 and erosion contact 6, with a nozzle constriction 9 and preferably for Storage of compressed gas provided, annular pressure chamber 10, which can be connected via an annular channel 11 provided between the erosion contact 6 and the inner wall of the insulating nozzle 8 and the nozzle constriction 9 to an exhaust chamber 12 located downstream of the nozzle constriction 9.
  • the contact piece 2 contains a sliding contact 14, which is coaxially encompassed by the nominal current contact 5 and connected to the nominal current contact 5 via electrically conductive webs 13, in which the pin-shaped erosion contact 7 is displaceably guided in the axial direction.
  • the current transfer from the sliding contact 14 to the erosion contact 7 is here by contact lamellae 15, the guiding of the erosion contact 7 is ensured by bearing rings 16 and 17 consisting of polytetrafluoroethylene, for example.
  • the upper end of the compression spring 20 is supported on the sliding contact 14.
  • a recess 21 which is arranged essentially downstream of the nozzle constriction 9 and in which a spring-loaded pawl 23 which cooperates with the latching part 18 through an opening 22 provided downstream of the nozzle constriction 9 is rotatably mounted.
  • a nose 24 cooperating with the pawl 23 is fastened on the inner surface of the rated current contact 5.
  • the switching piece 1 When switching off, the switching piece 1 is moved along the axis 3 by the drive, not shown. After a predetermined stroke, the two rated current contacts 4, 5 separate and the current to be switched off commutates into a current path formed by the erosion contacts 6, 7.
  • the erosion contact 7 held by the pawl 23 follows the contact piece 1 during this time at the same speed and with the compression spring 20 charged until the pawl 23, which acts as a ratchet, is rotated clockwise after hitting the fixed nose 24 after a predetermined period of time.
  • the latching part 20 and thus also the erosion contact 7 serving as the clamping part of a clamping mechanism are released. Under the action of the now charged compression spring 20, the erosion contact 7 reverses its direction of movement (right part of FIG.
  • a switching arc is obtained between the erosion contacts 6 and 7, which fills the pressure chamber 10 with heated insulating gas. After the nozzle constriction 9 has been released by the erosion contact 7, the switching arc is blown by the insulating gas stored in the pressure chamber 10 when the current is approaching a zero crossing and is extinguished.
  • the high contact separation speed ensures that the insulation distance between the two erosion contacts 6 and 7 is large enough to withstand the recurring voltage.
  • the contact separation speed is the limiting variable, which can be increased significantly in a simple manner compared to a comparable switch according to the prior art by the measures described, without excessively increasing the drive energy and without changing the quenching geometry of the contact arrangement.
  • an increased contact separation speed is achieved without changing the quenching behavior of the contact arrangement, in that a rack and pinion gear is used as the traveling element instead of a locking mechanism.
  • the rack and pinion gear has two gear wheels 25, 26, each rotatably mounted on the switching piece 2 about an azimuthally guided axis, and four gear racks 27 to 30 aligned parallel to the axis 3, of which the toothed racks 27 and 30, respectively, are located at the downstream end of the insulating nozzle 8 are attached and each with radially inward teeth with radially outward teeth of the gear 25 and 26 are engaged.
  • the toothed racks 28 and 29 are embedded on diametrically opposite outer surfaces of the erosion contact 7 which can be moved in the direction of the axis 3.
  • the movable contact piece 1 and thus also the racks 27 and 30 are guided upwards.
  • This upward movement is converted via the gears 25 and 26 on the racks 28 and 29 into a movement of the erosion contact 7 which takes place at the same speed but is directed in the opposite direction.
  • the erosion contacts 6 and 7 are then separated from one another while maintaining the extinguishing geometry of the contact arrangement at twice the drive speed.
